The human realm: the moving finale of Magical Land of Oz

The fish, the fox and the penguin: three of the weird and wonderful species from the final episode of Magical Land of Oz.

The thrill of the krill: giant super-organisms captured in 3D

Scientists on board our research vessel Investigator have 3D-modelled hundreds of millions of krill in giant swarm and noticed a puzzling gender imbalance.

Lost and found: Solving a shark mystery

Researchers have identified a new species of shark known only from specimens in collections.

Talking toxic blooms and mass fish deaths

We explore the science behind the recent toxic algae outbreak and the mass fish loss in the Murray Darling, and look at ways to manage it in the future.

Love fish? Choose a range when selecting seafood.

Our research shows that huge economic and environmental benefits could come from fully using fish now discarded. If all of the edible fish caught was kept and sold, both the sustainability and profitability of fishing would significantly improve.

Exploring Australia’s ‘other reefs’ south of Tasmania

In the cold southern oceans, underwater mountains support deep-sea reefs.

Cooee! Sound-testing 1200 metres beneath the waves

We're using an echolocator to watch the daily migration of sea life rise up from depths to feed at dusk and then return back to the depths at dawn. But some fish have oil-filled bladders rather than a gas bladder making their reflection weak and difficult to count. That's where our special camera comes in.

Here’s the seafood Australians eat (and what we should be eating)

Over 85 per cent of seafood caught in Australia is sustainable. However, just because a fish is sustainably caught, it doesn’t make it the most nutritious and healthy option – and vice versa. We've compared the two to see what seafood is both sustainable and nutritious.

Loose genes and haunted ecosystems: meet eDNA, environmental saviour

'Environmental DNA' tells the story of an ecosystem, the genetic signatures of plants, animals, fungi, microbes in a milieu that can be ‘snooped on’ by researchers to detect exotic species and contaminated waterways, and inform palaeoecology and marine conservation.

Tiny jellyfish discovery is bigger than you’d think

Our researchers have discovered and named two new species of micro-jellyfish found in Australian waters.

Love is in the water: Critically endangered handfish embrace art, new ceramic nests

The spotted handfish—the first marine fish to be declared Critically Endangered—is a Tasmanian treasure and we've just paired science with art to help bring them back from the brink.

We came we saw: saving the sawfish

Sawfish are critically endangered. We recently worked with Indigenous rangers to help save these sawsome fish!
